WINData conducts wind resource assessments to determine the meteorological and climactic characteristics of a site and from this analysis can estimate the potential power production and the impact to the project’s bottom line.
WINData provides met program design, data collection, data summaries, wind power output summaries, wind site analysis and professional meteorological certified reporting as per client requirements. Preliminarily, WINData can often determine a site’s seasonality and wind quality through a combination of a site visit, maps, and any existing site or regional data.
WINData site analysis is conducted using wind speed, wind direction, temperature, pressure and regional air density data gathered at or near the site’s location. Typically, wind flows vary over the complex terrain in a project area and it is crucial to have an experienced analyst conduct a topographically appropriate site study.
WINData wind site assessments provide project owners and designers with:
- The average wind speed over all the turbine locations for the project
- The maximum mean wind speed at the turbine location
- Mean Wind Speed
- Weibull Parameters and
- Turbulence Intensity
Other factors examined to determine the environmental conditions at the site include:
- Annual average ambient temperature
- Extreme minimum ambient temperature
- Extreme maximum ambient temperature
- Days of temperature below –17° C
- Days of temperature above 30° C
- Average relative humidity
- Height above sea level
The Weibull scale parameter and mean wind speed are used to determine the IEC Classification of the site and the subsequent classes of turbines that are suitable. The lower Weibull shape parameter indicates a large mean wind speed. The air density at the site is lower than at sea level, which will reduce the fatigue caused by the large mean wind speed.
If the temperatures on-site are very low, Low Temperature Option package are required from the turbine manufacturer and will be necessary for the best performance of the wind turbines at the project site. WINData uses the met data analysis to determine the size, number and manufacturer of wind turbines that will be used.
For each turbine, the following information is considered:
- Power Curve
- Technical specifications
- Tower type and proposed hub height
- Design life
- Level of certification achieved
- IEC design wind class (I, II or III)
- Summary of performance guarantees and warranty provided
WINData can lead the process for final wind turbine selection and generate turbine recommendations for the project site. As the turbine selection process proceeds, WINData can go out to the list the potential turbine vendors to determine the availability and delivery schedule and other aspect of the turbine supply process, and further, obtain firm pricing bids and negotiate TSA’s and MRO’s for equipment and for warranty, service, and maintenance agreements with the manufacturer.

WINData has focused on wind energy site prospecting throughout the US for over 22 years. WINData provides site prospecting services and creates value by conducting detailed site identification and resource analysis, securing development rights and demonstrating project viability.
WINData’s wind site prospecting personnel have long term expertise in desktop level studies, site topographical explorations and met program design of prospective windy real estate parcels. WINData provides project management for installation of met towers and instrumentation of a prospect site.
As part of the prospecting process, WINData experts explore the complexities or hidden attributes of the site to determine early critical path issues. WINData works with local entities, future power off-takers, and development entities from the outset to streamline the development process and build appropriate levels of awareness about a site’s potential.
Once site prospect is leased, met towers are installed and data is flowing into WINData’s servers, we continuously monitor and analyze data as a precursor to a full site assessment study which usually occurs after a year or more of data is collected.

Meteorological “Met” Towers
Possibly the most crucial step in the development of a potential wind site is the collection of accurate and verifiable wind data. WINData professional services comprise meteorological (“met”) tower design, installation and data integration to support end user requirements and forecasting data services.
WINData met towers and WINData professional installation services insure collection of “bankable” on-site wind data at hub heights up to 110 meters. Each met tower system installation is planned, specified and supervised by company engineers in conjunction with our clients’ in-house specialists. On-going support is available throughout the entire data collection period.
WINData sells and installs tilt-up, guyed lattice and SSV met towers to suit each customer specification – met towers up to 100 meters are available for either permanent or temporary installation.
WINData’s “WINDataNOW! SuperDuty® data collection towers” are available for sale, delivery and installation throughout continental North America. WINDataNOW!® towers are manufactured using high strength galvanized steel and are available in heights up to 60-meters.
WINDataNOW! SuperDuty® data collection towers are available for sale and installation throughout continental North America. WINDataNOW!® towers are manufactured using high strength galvanized steel and are available in heights of 20, 30, 40, 50 and 60-meters.
WINData® installs NRG NOW systems in 50M, 60M and 80M heights and offers Second Wind towers systems and instruments.
WINData® is a registered reseller, distributor and installer of Mega80 (formerly AAT – Groupe Ohmega) 60M, 67M and 80M Met Towers.
For Hub-height measurement WINData installs Sabre and Rohn guyed lattice towers and Self supporting SSV towers for heights of 65 to 110 meters (350 feet).
Wind and Climatological Sensors
Sensors are installed to measure wind speed, direction, temperature and barometric pressure at designated heights. Clients’ choice of industry standard sensors are available for purchase and installation.
